Inventor: ALVAREZ BERENGUER ANTONIO
IPC: B01J39/14
Filed: 1988-06-29
Abstract: The present invention refers to a process for bleach­ing and increasing the ion-exchange capability of the sepio­lite mineral, basically consisting of treating, at high pH and temperature, the sepiolite with a basic salt solution, which results in bleaching the starting material by dissolu­tion of the organic material present in it, and in increas­ing the ion-exchange capability by a structural transforma­tion of sepiolite. The bleaching can be optionally comple­ted with a reduction treatment with sodium dithionite or with other reducing agents capable of reducing Fe³⁺ to Fe²⁺.

Abstract: In a method of recording a data signal on an optical card (11) having a photosensitive layer applied on a metal layer, a number of light beams are emitted from a number of light sources (15), such as semiconductor laser diodes or thin film electroluminescent elements, each light source being selectively driven in accordance with the data signal to be recorded, and the light beams are simultaneously made incident upon the photosensitive layer via a projection optical system such as optical fibers and lens, while the optical card is moved in a longitudinal direction of the optical card. 
The recording light beams are aligned in a width direction perpendicular to the longitudinal direction. In this way optical cards can be manufactured quickly and cheaply in comparison to previously-proposed methods.

Filed: 1989-01-18
Abstract: A waveform improving apparatus improves the contour of a waveform of a first signal which has a reduced frequency band by using a control signal generated from a second signal which has a correlation to the first signal. A waveform adjusting circuit increases the level of the first signal waveform at the rising slope portion thereof and decreases the level of the first signal waveform at the falling slope portion thereof to obtain a waveform-­adjusted first signal. A control pulse generating circuit differentiates the second signal twice to obtain a control pulse having a predetermined duration and terminating at the center of a slope portion of the first signal wave­form. A sample/hold circuit is responsive to the control pulse for sampling a level of the waveform-adjusted first signal and holding the sampled level during the duration of the control pulse thereby obtaining a waveform improved first signal.

Abstract: An exposure method wherein a mask (8) and a semiconductor wafer (1) are disposed opposed to each other in a close proximity relation in respect to Z-axis direction and wherein a pattern of the mask is printed on each of different shot areas of the semiconductor wafer in a step-and-repeat manner, with a predetermined exposure energy, is disclosed. In this method, the spacing between the mask and the wafer for the paralleling of them is made larger than the spacing therebetween as assumed at the time of mask-to-wafer alignment in respect to X-Y plane or the spacing between the mask and the wafer as assumed at the time of exposure of the wafer to the mask. After the paralleling of the mask and the wafer, the mask and the wafer are relatively moved closer to each other in the Z-axis direction and the alignment and exposure is performed. This ensures that the alignment and exposure is effected at an optimum spacing while, on the other hand, contact of the mask and the wafer at the time of paralleling is precluded.

Abstract: A photographic system comprises a camera and a film structure which can be loaded in the camera and in which photographing data can be recorded. The film structure has an image recording section in which a photographed image is recorded and a memory means for storing therein identification data peculiar to the film structure. And the camera inputs the identification data stored in the film structure into the camera and judges according to the inputted identification data whether the film structure is fit for the camera or not. Thereby, the photographing data can be recorded or read only when the film structure is fit for the camera. A film structure also can be loaded in a camera having peculiar identification data so that it is judged whether the film structure is fit for the camera or not.
